I do Zumba 2-3 times a week for around an hour each time and I ADORE it; however I am pretty sure I need another exercise as I'm suffering some strain (I'm pretty certain it's from overuse) in my upper-back-shoulder-neck area.

My problem is, I don't really care for any other exercise. Running and walking are not my cup of tea (especially in this weather!), and I don't have a YWCA or a rec center closer than 50 miles away to attend so it really has to be at home stuff with no special equipment. I'm considering trying Pilates again. I did it a couple of times a few years ago and it was alright.

Do you guys have any suggestions for a fun workout for a Zumba addict?

Oh, I'm sorry, I should have explained...It's a cardio dance workout based on Latin rhythms and beats. It's a lot of fun, if you ever have the chance to try it I would definitely recommend it...it's a real calorie blaster, too.

I've never tried zumba but I've heard lots about it.
I would definitely recommend yoga. After I started running, I realized I needed something to counter all the aches and strains. Yoga is absolutely perfect and it would be a really nice to alternate it with zumba since the latter is so high paced and the former is so calming. Kind of a ying-yang sorta deal

I also adore Zumba. I recommend you to include a little more upper body warm up (arms circle...etc) and 10-15 min yoga stretching at the end. Yoga is really great for cool down to avoid all sorts of pain.

If you want another dance program the Hip hop abs is good one. Its for whole body (not just abs) with hiphop music (logically, eh ). Maybe you also like belly dancing. I've not tried any but Ive heard its fun.

I also love Zumba. I just recently tried Cardio Ballroom with Julianne (from Dancing with the Stars). If you like Zumba, try one of the other dance oriented workout videos. As Moyca said, there's hip-hop and ballroom and everything in between...

ChelsKay, are you using (shimmy?) weights at Sculpt & Tone? This also could be the reason for your strain. Try without weights.
In program are too many, too quick, disorientation moves without proper form which aren't good for elbows/sholders. (People always lift weights slowly, steady with flat back at fitness - and there is a reason why!)
